Sample SACE Year 12 Chemistry questions

These sample questions are visible on the page before login. They show SACE Year 12 Chemistry titration curves, equilibrium shifts, electrochemical cells, organic reactions, spectra, and kinetic data with diagrams, tables, curves, and spectra before opening the demo.

SACE Year 12 Chemistry Titration analysis hard titration curve

1. A titration curve has a near-vertical section where indicator colour changes. Which part should the indicator range match?

Choices

The steep section near equivalence
Only the flat starting region
Only after all solution evaporates
The mass spectrum axis

Explanation:

An indicator is useful when its colour-change range lies within the steep pH change around equivalence.

SACE Year 12 Chemistry Equilibrium hard equilibrium diagram

2. A cobalt complex equilibrium turns bluer when chloride ion concentration is increased. Which side is favoured?

Choices

The blue chloride complex
Only water molecules
No complex ions
The pH 7 point only

Explanation:

Adding chloride favours the side that consumes chloride ions.

SACE Year 12 Chemistry Electrochemistry hard electrochemical cell

3. An electrolytic-cell diagram shows metal ions gaining electrons at one electrode. What process occurs there?

Choices

Reduction
Oxidation
Esterification
Chromatography

Explanation:

Reduction is gain of electrons, so metal ions gaining electrons are being reduced.

SACE Year 12 Chemistry Organic and biological chemistry hard organic pathway

4. An ester hydrolysis pathway shows ethyl ethanoate reacting with water. Which pair of product types is formed?

Choices

A carboxylic acid and an alcohol
Two alkenes
A metal and a salt bridge
Only carbon dioxide

Explanation:

Hydrolysis of an ester splits it into the corresponding carboxylic acid and alcohol.

SACE Year 12 Chemistry Analysis hard mass spectrum

5. A spectrum labels the highest m/z peak as M+. What does M+ usually represent?

Choices

The molecular ion
The pH endpoint
The anode only
A chloride ion only

Explanation:

M+ is the ionised whole molecule, so it is used to infer molecular mass.

SACE Year 12 Chemistry Kinetics hard rate graph

6. A rate graph compares the same reaction at 20 C and 40 C. The 40 C curve rises faster. Which value is larger at 40 C?

Choices

The rate constant
The number of atoms destroyed
The molecular mass of every reactant
The equivalence volume must be zero

Explanation:

A higher temperature usually increases the rate constant because more collisions exceed activation energy.

For parents comparing SACE Year 12 Chemistry support

SACE Year 12 Chemistry practice should help students connect chemical reasoning to visible evidence: titration curves, equilibrium shifts, electrochemical cells, organic reactions, spectra, and kinetic data. These examples preview that visual reasoning before the no-login Chemistry demo.
